We are adding more functions tapping on the information flowing on the bus, of course these are now written in Clojure... Census tracking, decentralized service request management, ... This year the bus will also extend to interconnect other hospital services. The bus is also a way to convince users to move to a paperless environment and focus on data entry completeness to achieve that goal. We have also in the works a Clojure/Terracotta/Java messaging layer to improve parallelism. This should be rolled out in summer time. Transitioning to Clojure V1.0 was not a problem and we do not expect that moving 1.1 will prove difficult. The bus is still running on a cluster of small foot print computers but we moved to Atom 330 motherboards to boost processing power. This thing will celebrate it's first year in production very soon without significant pain and this a proof to me that Clojure is mature.

Re: roll call of production use?
We picked one that met our minimal requirements... our prototype was in Java however and that probably biased the choice a bit. But for us it's an intermediate step. We need a more flexible solution. We will keep ActiveMQ in the picture to link different clusters (or an alternative) but for intra cluster processing we want something more in line with the contraints we need to meet especially regarding event serialization. We think that custom fit message serialization is not easily managed using a message bus generic layer. We need a more specific solution and some management hooks to deal with this in day to day operations.

I have done a smallish project (mainly to stop my friend doing some monkey work) - it basically opened an ms excel spreadsheet (using library developed by apache project folk), validated input, categorised groups of rows by needed criteria and wrote the results to a new spread-sheet (formated), with interesting results on separate page (these were done by hand before). In the proces, I have re-written the application once (as I learnt more over time + switched to apache library for excel files) and was very pleased with the result (the code) - both, performance and beauty.

Re: roll call of production use?
I have written a production web app with compojure. It was a very nice experience. First project I have pulled of totally TDD and the functional aspect of clojure really makes tests so much easier and more truthful, although there sometimes seems to sneak in some exceptions I didn't expect from the java side. It was a small ad campaign site with some SMS functionality, with web pages formatted for mobile phones. Really nice to be able to just wrap our java libs for sending SMS and device recognition. The compojure HTML generator is fantastic, extremely powerful and easy to use. I am amazed how compact the end code is. I deployed a war file on tomcat 5.5. The app is stable and very fast. One thing I would have liked to have was to start swank-server from the war to provide an easy way to do hot updates and inspection, but I ran into some problem with *1 etc not being defined so I gave up on that. I prefer to deploy a war because I did not want to write my own init.d script and bug test that. Overall - a very nice experience. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: roll call of production use?
We're maintaining a large database of tagged images and had a need to perform fuzzy search of the database. The existing search tool takes exact queries only. So it was necessary to hack up a little tool to sit between the query source and the engine and transform the query into a fuzzy query. You can think of it like this: the input query is something like x AND y and the output is something like (x AND (y OR y2 OR y3)) OR (y AND (x OR x2 OR x3)) where y2 and y3 are in some sense near y and x2 and x3 near x. The query transformation is simple enough, but it was really handy being able to test it at a REPL, and even hot-swap modifications and do live testing and tweaking of e.g. the neighborhood graphs used to fuzzify query terms. (Right now it only allows slop in one query term; sort of a Hamming-distance-1 matcher. Extending it further would invite a combinatorical explosion as well as lead to noisier, less useful results. Distance 1 seems to be the sweet spot for our app.) The code takes the input query, takes apart the terms, and generates seqs of alternatives, with some (butlast (interleave foo (repeat OR))) type stuff here and there, and cobbles them together again using seq functions, str, and java.lang.String methods. (Some query terms need to be parsed, e.g. are a hyphenated entity the first part of which should be fuzzy-matchable while the second part should stay constant, etc.) Rather boring? Little things like this incrementally improve services. Two guys hacking like this in their garage went on to start Google. :) We don't have such lofty aspirations, but it's still something to keep in mind. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: roll call of production use?
I've deployed two small mashup apps which combine OpenCalais and our content repository to annotate documents with metadata (named entities, relationships, etc) and expose the results over the web. Good experiences all around, including with the clojure-http-client and saxon wrapper libs + Compojure. I did miss having a nice Clojure RDF lib, so maybe I'll make a Jena wrapper in the future.

Re: roll call of production use?
At my workplace (University of Houston, dept. of Health and Human Performance) Clojure is our primary language for interacting with our virtual world presence in Second Life. We have an automated lesson path building system currently in production, and several other projects in various states. automated lesson path building system - user (currently it's too scratchy to turn the profs loose on this, so I always use it) draws a learning path out in a 2D swing based clojure app. It compiles a set of 'prims' that fill the needed shapes (a sort of variation on the knapsack problem, where you also get a small 'rubber' block that can fill in small spaces, but it's an optimal packing problem), creates the textures, controls a C# robot (no java libs for that task) to upload the textures, and sends commands to a robot in-world to do the actual build. Nutrition Goggles system - What I should be doing today, if I weren't noodling around in Clojure 8cD (OK, in theory the injectable agent system I'm doing today should be usable for all these projects) This is a HUD (tool that attaches to the users screen as additional UI), when they look at a food item in the virtual environment it shows the nutrition data. They also can enter nutrition data the same way. Back end in clojure. Summoner monitor system - I'm supposed to write this, I'd dearly love to get there, as it's a tool that alerts me that I'm needed in world to help a student. (currently I depend on my email alerter, which is suboptimal) Configurable teleporting sign system - a web app that lets users set up teleporters around the campus sim, while retaining some control over the appearance of the central entry area.

I've thrown together a small clojure program to present an internal dashboard of active projects and states and stuff. Having the JVM was invaluable, since I could easily make postgreSQL queries as well as use JGit to walk the history of a git repository. I've mentioned this before, but http://github.com/d3zd3z/webweight is a small program I wrote to learn compojure. One significant part is that I've written an org.davidb.contrib.html and xml that wrap around the same data structure used by clojure.xml. It allows for easier construction of html/xml in code: (html/table :border 1 (html/tr (html/td :valign top Cell) ..))

Re: roll call of production use?
i'd be interested to hear who has successfully used clojure in production. Hello, 1- We have this license server, used to control the use of a professional software (this one written using delphi). This was tested with thousands of simutaneous connections, and has been working with no hiccup for 6 months. It uses nio + ssl + a mysql database. 2- An application that connects to telephony switches and gives real time call informations to web users. With the whole administration part (managing customer, agents and their different price lists, showing statistics). It has many users permanently logged in as they need to monitor those calls (they are call shops). So they can see the calls counting for their (typically 8) booths, and can do various operation on the calls (like interrupting a prepaid call for instance). That's a lot of polling. We're still in the ramp-up period so we only have a fraction of the existing customers using our application yet. This project uses compojure + jetty + ssl + a postgres database. There isn't much to report, everything worked as expected. The jvm integration was a big help, providing access to some java third party libraries. Also using java, i can develop on windows, and just drop the jar on a solaris or linux server, it just works. The REPL helps a lot too. I'd like to see support for database connection pooling, and those pesky sql underscored column names to end up with dashes on the clojure side. Also compojure has somewhat of an attitude. Actually i miss cl-sql and hunchentooth, but hey you can't get everything, and what we've got is already fantastic. The language itself is perfect for the job, though i'm looking forward to the protocols and deftype extensions. The type metadata trick always seems wrong, and including it in a map feels like a hack. Refs, atoms and agents helped a lot, as well as the immutable data structures.

In that case, I'd suggest you look first at Red Hat (market cap: $5.09B), and the Linux community's attitude towards them (generally positive). Oh, I have no problem with making money by using open source software, when it's done in the manner that companies like Red Hat do it. It's the use to lock down some piece of proprietary software even more than it already is that seems, at the very least, ironic. -- You received this message because you are subscribed to the Google Groups Clojure group.
